Avionics / Garmin GFC 500/600
The Garmin GFC 500 and GFC 600 have become the go-to autopilot upgrades for owners replacing aging legacy systems. Michigan Aviation installs both at Oakland County International Airport, with the panel, display, and navigator integration planned as one coordinated project.

What We Offer
Why GFC
Beyond smooth digital control, the GFC series adds safety features legacy autopilots never had, including envelope protection, a dedicated LVL button that returns the aircraft to level flight, and coupled approaches with your GPS navigator. For many owners it is the single most meaningful safety upgrade available for the airplane.
Autopilot projects work best when the whole panel is considered together. The GFC 500 requires a compatible Garmin display, so many owners pair it with a G3X Touch retrofit or TXi display upgrade in a single visit, reducing downtime and total labor.
FAQ

The GFC 500 is designed for light piston singles and pairs with a G5, G3X Touch, or TXi display. The GFC 600 is a standalone autopilot for high-performance piston and turbine aircraft that interfaces with a broader range of equipment.
In most eligible aircraft, yes. Many owners replace aging legacy autopilots with the GFC 500 for smoother performance, envelope protection, and far better parts availability. We review your current installation and plan the swap.
The GFC 500 requires a compatible Garmin display such as a G5, G3X Touch, or TXi to function. If your panel does not have one yet, we plan the display and autopilot as a single coordinated installation.
